When the content of the component (a1) is less than or equal to the above upper limit value, it is possible to prevent the handleability from being deteriorated due to the viscosity of the microgel particle group becoming too high. When the content of the component (a1) is equal to or higher than the lower limit, a microgel particle group is easily obtained.

For dissolution, the component (a1) is preferably dissolved in an aqueous solvent at a temperature equal to or higher than the melting point.

  The component (A) forms this crosslinked solution from the component (a1) and the component (a2) by adding the component (a2) or by adding the component (a2) and cooling, and includes the crosslinked product. It is produced by simultaneously shearing and crushing the gel, whereby a micro-gel aggregate having fluidity and yield value can be obtained. In this case, the cooling may be basically performed by any method, but cooling by a blending tank jacket, a method of introducing a cooling coil, cooling by external circulation, etc. may be mentioned.

  The cooling rate is preferably 0.05 ° C./min or more, and more preferably 0.1 ° C./min or more. When the cooling rate is less than 0.05 ° C./min, it takes too much time for cooling, and the production efficiency may deteriorate. The upper limit of the cooling rate is not particularly limited, and even if the cooling rate is large, there is no influence on the quality of the kitchen detergent composition obtained as long as cooling is performed while applying a shearing force.

The component (a2) may be added before cooling or after cooling is stopped, but is preferably added before reaching 40 ° C.

  In the present invention, the degree of shearing and crushing during gelation can be appropriately adjusted according to the required average particle diameter of the microgel particle group. When a smoother appearance is required, it is sufficiently crushed by high-speed stirring to form a microgel particle group with a fine particle size. When added, it is preferable to reduce the degree of crushing by light agitation to form a slightly larger microgel particle group. The shearing force is not particularly limited, but a stronger shearing force is preferable to a weaker shearing force for the purpose of normal uniform mixing. Specifically, the lower limit of the shear force is preferably 2 m / s or more, and more preferably 3 m / s or more. The upper limit of the shear force is preferably 30 m / s or less, and more preferably 25 m / s or less. If the shearing force during gelation is less than 2 m / s, there is a possibility that the whole gels without forming a microgel particle group, and if it is too large, an effect commensurate with it cannot be obtained.

When the tip speed is in such a range, an aggregate having a large component (A) can be obtained by gentle stirring.

  The content of the component (A) is preferably 10 to 50% by mass, more preferably 15 to 35% by mass, and still more preferably 20 to 30% by mass with respect to the total mass of the kitchen cleaner composition. When the content of the component (A) is not more than the above upper limit value, it is possible to suppress the deterioration of the detergency and foaming durability. When the content of the component (A) is equal to or higher than the lower limit, it is easy to improve the detergency and foaming sustainability.
